Abstract
Abstract Let ( N ,ℝ, θ ) be a centrally ergodic W* dynamical system. When N is not a factor, we show that for each nonzero real number t , the crossed product induced by the time t automorphism θ t is not a factor if and only if there exist a rational number r and an eigenvalue s of the restriction of θ to the center of N , such that rst =2 π . In the C* setting, minimality seems to be the notion corresponding to central ergodicity. We show that if ( A ,ℝ, α ) is a minimal unital C* dynamical system and A is not simple, then, for each nonzero real number t , the crossed product induced by the time t automorphism α t is not simple if there exist a rational number r and an eigenvalue s of the restriction of α to the center of A , such that rst =2 π . The converse is true if, in addition, A is commutative or prime.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
